I mantain a github fork of the "official" repo on github. This fork differs from the original repo only in the extent that a debian build setup for creating the package is incorporated. Basically it's a debianization of the official version. The official debian version available on unstable (sid) lags considerably from the current development version.

FAQ

What about Ubuntu?

I don't know. The distribution release policy in Ubuntu is a mere marketing ploy. What's unstable? What's stable? What's testing? You can try to install these packages. I presume it's safe. If you prefer to use a repository that follows the "Ubuntu way" then try Brian Mercer's launchpad PPA for Nginx.
